Empty, unclickable fields when trying to create a build target?

Description of issue:

I have been trying to set up my first cloud build project. I created a project ID under the Unity Developer Console and enabled the Cloud Build service. I provided the Mercurial login for accessing my repo.

Then it asked me to setup a build target. I selected Android, and then it brought me to a non-functional form entry. I can type in the Target Label and Project Subfolder fields, but both the Platform and Unity Version dropdowns are empty and there are no options to select. At that point, I can't proceed. Clicking Next does nothing.

I have also tried creating other targets (iOS and Web) with the same results. I have also tried doing target setup from the Unity Editor itself with the same results. Interestingly, in the editor, the two checkboxes at the bottom are labeled "{{UTCHECKBOXLABEL}}"

I have a Pro license. Other details:

Unity version: 5.5.0f3 64-bit

Source control: Mercurial on Bitbucket

Local build platform: Win 10

Build target: All

Something seems to be very wrong. Can anyone tell me what's going on?

 

Thanks! It seems to be working now

 

I still have this issue
Also using mercurial.
